You can find many of the more commonly used modules in .rpm format (including DBI). If you want to install from the source, however, you can do "perl -MCPAN -e 'install (module-name)'" from the command line. For example, to install DBI you would do: perl -MCPAN -e 'install DBI'. Or you can always download the modules from the CPAN and compile them yourself. Just go to www.perl.com and follow the links to the CPAN to get to the modules.
